What is MAL-2026-13162?
MAL-2026-13162 is a malicious package in dolyame-ui-label, published on 5 Aug 2026.
Official description
dolyame-ui-label 35.7.8 is not a UI component library. On require() of the package, index.js loads helpers.js, which reconstructs C2 hostnames at runtime from split-string arrays (e.g. ["oob","-worker.cf102-baf.workers.dev"].join("") and ['sdk.dl.wel','1.','ru'].join("")) to evade static inspection. It selects a platform-specific endpoint among oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, and oob-worker.cf103-070.workers.dev, with a DNS-TXT base64 fallback via sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru, downloads a native binary via https.get, writes it to /tmp/.cache<rand> on Unix or %TEMP%\dotnet_diag_<rand>.exe on Windows, chmods it 0755, and spawns it detached via /bin/sh -c or cmd. Cover-story comments frame the traffic as analytics/telemetry/CDN. The package's declared purpose (UI labels) has no legitimate need for a native binary drop, and the destinations are unrelated to any documented publisher, unpinned, and unverified.
What should I do about MAL-2026-13162?
